SHEFFIELD, England (AP) _ Yugoslavia's team was given a belated welcome to the World University Games on Monday after being accidentally shut out of Sunday's opening ceremony.

Officials believing that the 16 competitors and officials had not arrived because of civil strife at home, did not have a flag and banner available hand when the team stood outside the Don Valley stadium waiting to join the parade.

While the other 110 teams toured the stadium, the Yugoslavs could only watch and on Monday they received an apology from Ray Gridley, the Director of Games Administration.

Gridley said he accepted full responsibility for the misunderstanding, although the fault lay with technical people who thought Yugoslavia had dropped out of the Games.

''Every effort is being made to make amends,'' Gridley said. ''We have the Yugoslav flag flying in the Don Valley Stadium and they are fully welcome in the Games.''

University Games officials also were surprised to see a Lebanese team of 20 competitors and officials arrive for the event.

Months ago an invitation to compete arrived from Lebanon marked ''Headquarters blown up - return to sender.''

When a totally unexpected Lebanese group arrived, organizers had to hurriedly find accommodation and a flag for the opening ceremony.

Britain's team officials defended a controversial decision to charge each of their competitors $160 to take part in the 16th University Games.

The policy apparently caused resentment among some of Britain's 306 competitors at the 12-day event. But Mike Lamb, secretary of the British Students Sports Federation, said the athletes had expected to pay something towards the cost of their participation at every University Games for the last 20 years.

''It is a token of what the BSSF invest in these athletes and it is used to offset the massive preparation programme we have undertaken with our team,'' Lamb said.

It's not uncommon for a father and son to be associated with the same team.

But Uruguay's soccer goalie, 23-year-old Anibal Paz, is being coached by his grandfather, who was in goal when his country beat Brazil to win the 1950 pro World Cup.

Anibal Paz Sr. regularly has coached the student team's goalkeepers.
